Ok. To read records from XML, use the classes provided in System.Xml name space. Work with XmlDocument[^] and load the XML to it. XmlDocument class provides methods to get collection of nodes. Start a loop that iterates over the collection.
To insert data into SQL database, you need to prepare insert SQL statement with necessary parameters. Then work with SqlConnection, SqlCommand classes. Execute the DB statement in each iteration of the loop. If you want to avoid duplicate records, create a primary key on the database table and when you try to insert duplicate records, SQL server will throw exception. Handle this and proceed to next row.
All the classes which I explained has got very neat documentation and you should be able to start easily.

While searching on the Internet is good, as a fresher you should be learning stuff initially from a book. Not all the stuff in Internet are correct and reading from a book makes real difference. So I suggest you to get a good book on the subject and start working with the examples rather than wasting time on online forums or doing search.

When you post questions you should identify correct forum.

Your question is terribly unclear and off topic to this forum. If your question has anything to do with ASP.NET, explain it clearly. If not, move to correct forum.

No way... If you are talking about process in the client side, it cant detect it from the browser.. As browser only deals with htmls(Request / Response). It dont have access to anything, but just to display some Data and Ui elements.
If you are looking for server side processes, it is very easier to deal with this. Just use
System.Diagnostics.Process[] processlist = System.Diagnostics.Process.GetProcesses()
But I dont think your motive is fulfilled using this as no one opens internet explorer to work with their own site in the server.
Anyway.. Be specific on what you require always. And post in right section.
Cheers.

I doubt this. ASP.NET process runs on a restricted account and will not have full trust. GetProcesses() method is likely to fail if invoked from ASP.NET application.

Yes.. But I guess giving proper rights to the user (or impersonating) to run the aspnet worker process as an administrator will surely solves the issue ..
But seriously... this is not generally what we do often... but it is possible I guess.
Cheers..

Why do you need that ? Do you need it for an ASP.NET Application or any win Application ?

Then You better ask third pary tool developing team..!
As you are using the 3rd party tool first check tht it is supported for such type..!
BTW You didnt mention the 3 rd party vendor name so tht if any one uses the 3rd party tool before they can help You..!

thnx again
in my web site i want to use some windows form features so for tht i am inclunding one page which is basically windows form for tht i am using webgui visual studio express which run my application in web.
so i want to pass querystring from my web application page to this windows app page which is basically .wgx page

What is the problem.... load the page using Webbrowser control of your windows application and invoke the items which you need to get the querystring...
For example :
Say I add a Webbrowser control on my form,
now during form load I pass
wbrowser.Navigate(new Uri("http://codeproject.com"));
Next I navigate to an article. You might invoke browser buttons to navigate. Finally to get the querystring you use :
wbrowser.Url.Query
I hope this is what you needed.
Next time post in right section.

thumb.Save(thumbnailFilePath, codec, eParams);
}
}
}
}
catch (Exception ex)

return FileName;

//it will return the file name with resize.

thanks for the code
what about the functon of
GetImageCodec(Extension)
you dont declare this function.
|
|
|
|
|
private static ImageCodecInfo GetImageCodec(string Ext)
{
switch (Ext)
{
case ".jpg":
return ImageCodecInfo.GetImageEncoders()[1];
case ".gif":
return ImageCodecInfo.GetImageEncoders()[2];
case ".bmp":
return ImageCodecInfo.GetImageEncoders()[0];
case ".png":
return ImageCodecInfo.GetImageEncoders()[4];
case ".jpeg":
return ImageCodecInfo.GetImageEncoders()[1];
case ".tif":
return ImageCodecInfo.GetImageEncoders()[3];
case ".jpe":
return ImageCodecInfo.GetImageEncoders()[1];
case ".jfif":
return ImageCodecInfo.GetImageEncoders()[1];
case ".tiff":
return ImageCodecInfo.GetImageEncoders()[3];
default:
return ImageCodecInfo.GetImageEncoders()[1];
}
}
